how can you prepare 100ml of a 1.1m scandium (111) Bromide Solution From a 2m stack solution?

Answer 1

V1C1 V2C2

V1 = initial volume = x ml

C1 = initial concentration = 2 m

V2 = final volume = 100 ml

C2 = final concentration = 1.1 m

Substitute in the values...

(x ml)(2 m) = (100 ml)(1.1 m)

x = 55 ml of 2 m diluted to 100 ml
